Residual Stress From Cold Expansion of Fastener Holes: Measurement, Eigenstrain, and Process Finite Element Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cold expansion (CX) is a material processing technique that has been widely used in the aircraft industry to enhance fatigue life of structural components containing holes. CX introduces compressive hoop residual stresses ...
Biaxial Residual Stress Mapping for a Dissimilar Metal Welded Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a sequence of residual stress measurements made to determine a twodimensional map of biaxial residual stress in a nozzle mockup having two welds, one a dissimilar metal (DM) weld and the other a stainless ...
Effect of Collagen Fiber Tortuosity Distribution on the Mechanical Response of Arterial Tissues
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigated the effect of collagen fiber tortuosity distribution on the biomechanical failure and prefailure properties of arterial wall tissue. An in-silico model of the arterial wall was developed using data ...
Measured Biaxial Residual Stress Maps in a Stainless Steel Weld
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a sequence of residual stress measurements made to determine a twodimensional map of biaxial residual stress in a stainless steel weld. A long stainless steel (316L) plate with an eightpass groove weld ...
Assessment of Mechanical Properties and Microstructure Characterizing Techniques in Their Ability to Quantify Amount of Cold Work in 316L Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress corrosion cracking (SCC) behavior is a matter of concern for structural materials, namely, stainless steels and nickel alloys, in nuclear power plants. High levels of cold work (CW) have shown to both reduce crack ...
Assessment of Weld Residual Stress Measurement Precision: Mock Up Design and Results for the Contour Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experimental work has shown residual stress measurements in welded material to be difficult. To better assess the precision of residual stress measurement techniques, a measurement article was designed to allow ...
